Carson wants a smartwatch. He has an Android phone. Leo says that smartwatches are essentially side cars for mobile phones and for Android, the Samsung Gear S3 is a great option. It depends what he wants the smartphone for, though.
Is there one he could get for under $150? Leo says Android Wear is fine for around that price. The Asus ZenWatch 2 is very good. But he'll want to make sure he likes the size of it, because they tend to be big.
